About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX80-75S
The AirTAC SAIJ160X80-75-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 5 to 80 mm, allowing you to dial back the nominal 80 mm stroke by up to 75 mm during commissioning without adding external stops. Built with a SUS420J2 stainless steel rod and PT tapered ports, it handles heavy loads up to 9425 N pull force at 0.5 MPa.
This adjustable-stroke design is ideal for product changeovers on automated lines. The rear screw acts as a travel stop for end-position tuning, not a load-holding lock, so live air is still required to maintain position. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet works directly with AirTAC CMSE reed and DMSE solid-state switches.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX80-75S Is Used
Machine Changeover
Quickly reconfigure the end-of-stroke position for different product sizes on a single line, using the 75 mm adjustment range instead of swapping the entire actuator.
Pressing Operations
Fine-tune the exact bottoming position during commissioning to ensure precise contact force, leveraging the 18095 N push force at 0.9 MPa.
Heavy Material Handling
Move heavy pallets or components using the robust 40 mm SUS420J2 stainless steel rod, which resists corrosion and withstands demanding industrial environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX80-75S the Right Cylinder?
Choose this 160 mm bore when your application requires substantial thrust, such as 14074 N push at 0.7 MPa, but demands flexible end-stop positioning. If you need less force, stepping down to a 125 mm bore yields 5734 N pull at 0.5 MPa, whereas moving up to a 200 mm bore provides 15080 N pull at 0.5 MPa. The 75 mm adjustment range is perfect for prototyping or variable product sizes, whereas a fixed-stroke SAI cylinder is better for dedicated, single-purpose machinery.
For an exact ISO 15552 replacement match, specify: 160 mm bore, 80 mm stroke, 75 mm adjustment, PT port thread, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the 40 mm diameter rod and M36x2 thread carry high side-load capacity, this cylinder handles robust dynamics, though an external guide is still recommended for heavy radial loads. If you need true load-holding without live air pressure, consider the SAIL or BSAI series instead.

- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ160 Adjustable Cylinder SAIJ160AX80-75S FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from 80 mm down to as little as 5 mm. It sets the travel end and deceleration point, but it does not lock or hold the load without live air pressure.
At 0.5 MPa, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 2050 kgf of thrust.
